IMPORTANT: This website provides screening tools, not medical diagnoses.

1. No Medical Advice

The contents of ColorBlindTests.net, including text, graphics, images, and other material ("Content"), are for informational and educational purposes only. The Content is not intended to be a substitute for professional medical advice, diagnosis, or treatment.

2. Screening vs. Diagnosis

The online tests provided on this site (including the Ishihara Test, Red-Green Test, and Blue-Yellow Test) are designed as preliminary screening tools. While we strive for accuracy, online tests have inherent limitations due to:

  • Variations in screen color calibration and brightness
  • Lighting conditions in your environment
  • Distance from the screen

Therefore, a "pass" or "fail" result on this website does not constitute a medical diagnosis of color blindness or normal vision.

3. Consult a Professional

Always seek the advice of your physician, optometrist, ophthalmologist, or other qualified health provider with any questions you may have regarding a medical condition. Never disregard professional medical advice or delay in seeking it because of something you have read on this website.

If your test results suggest potential color vision deficiency, we strongly recommend scheduling a comprehensive eye examination with a qualified eye care professional.

4. No Doctor-Patient Relationship

Use of this website does not establish a doctor-patient relationship. We do not collect or store your personal health data for diagnostic purposes.
